When I came back home after not visiting for many years, I found that my sister was still not working or going to school and preferred to stay at home all day. She wore loose clothes, was mean to our mother, and acted inappropriately. She seemed to have given up on life and lost interest in everything.

However, I was the one who ended up doing something wrong with my sister. I was so excited when I saw her big breasts hidden under her tight t-shirt that I had sex with her, and for the first time in many years, my sister became sexually aroused. She was so horny that I felt like she was attacking me in my sleep.
